Pulmonary sarcoidosis is characterized by the accumulation in the lower respiratory tract of large numbers of activated CD4 T cells and elevated ratio of CD4/CD8 in bronchoalveolar lavage fluid (BALF). To study the value of CD4/CD8 ratio in BALF in the diagnosis of pulmonary sarcoidosis, we measured T cell subsets in BALF of patients with pulmonary sarcoidosis. The CD4/CD8 ratio in the patients (7.5 +/- 4.3) was significantly higher than that of the controls (2.1 +/- 0.7). The sensitivity and specificity of CD4/CD8 ratio in BALF for the diagnosis of sarcoidosis were 86% and 100%, respectively. We found that the CD4/CD8 ratio in BALF plays an important role in the diagnosis of pulmonary sarcoidosis. The analysis of CD4 in BALF may be useful in assessing the activity of sarcoidosis. The measurement of the CD4/CD8 ratio may be used to determine prognosis of pulmonary sarcoidosis.

D016516	CD4-CD8 Ratio	Ratio of T-LYMPHOCYTES that express the CD4 ANTIGEN to those that express the CD8 ANTIGEN. This value is commonly assessed in the diagnosis and staging of diseases affecting the IMMUNE SYSTEM including HIV INFECTIONS.	T4-T8 Ratio,CD4 CD8 Ratio,CD4-CD8 Ratios,T4 T8 Ratio,T4-T8 Ratios
D017565	Sarcoidosis, Pulmonary	Sarcoidosis affecting predominantly the lungs, the site most frequently involved and most commonly causing morbidity and mortality in sarcoidosis. Pulmonary sarcoidosis is characterized by sharply circumscribed granulomas in the alveolar, bronchial, and vascular walls, composed of tightly packed cells derived from the mononuclear phagocyte system. The clinical symptoms when present are dyspnea upon exertion, nonproductive cough, and wheezing.
